K&N Light Duty Synthetic Air Filter Cleaning Instructions

No Oil Required K&N Hybrid Air Filter Technology


  1. REMOVE FILTER: Remove the air filter from the intake pipe, the OE airbox, or the custom assembly. Handling carefully, lightly tap off all loose dirt and debris.
  2. APPLY CLEANER: Liberally spray K&N Synthetic Air Filter Cleaner onto both sides of the filter, with the majority of it applied to the dirty side. Allow to soak in for 10 minutes. Do not allow it to dry on the air filter.
  3. RINSE FILTER: Rinse off the filter element with cool or warm (not hot) water from the clean side out in order to flush the dirt out of the filter. It may be necessary to use your fingers on the hose, to apply light water pressure. Repeat steps 2 and 3, until the water flowing through the media is completely clear of any dirt and debris.
  4. DRY AND RE-INSTALL FILTER: After rinsing, gently shake off excess water. Allow filter to dry naturally, or use compressed air to speed the drying cycle. The filter should be dry, or just slightly damp before re-installing. Re-install the filter onto the intake system or into the airbox once it is dry. Follow all original installation instructions.
